    摘要: A method of dynamic frame presentation improvement for liquid crystal display is disclosed. The method comprises the step of providing a gray level mapping table, which maps the signal gray levels from 0 to N into mapped gray levels from 1 to N−1 level. Thereafter, the mapped data is fed into over-voltage compensation circuit. The over-voltage compensation circuit then implements process of the gray level ascending or gray level descending while the previous frame turns into current frame with a varied gray level.

    摘要: A multi-frame overdriving circuit for use in a liquid crystal display including a counting unit and a multi-frame overdriving unit is provided. The counting unit counts a number m of frame periods for which a pixel data corresponding to a pixel keeps a first gray value, wherein m is a positive integer. When the pixel data changes to a second gray value from the first gray value in a first frame period, the multi-frame overdriving unit respectively outputs y multi-frame overdriving pixel data corresponding to the pixel within successive y frame periods starting from the first frame period. The y multi-frame overdriving pixel data are related to the first gray value, the second gray value and the number m of frame periods, wherein y is a positive integer.
